Installation Requirements: The hand controls require a medium level of installation effort using basic tools. No soldering, cutting, or modifications are necessary. Please review the Installation Instructions for details. Please contact us at SimAbility@Outlook.com if you are not comfortable with completing this installation and we can arrange to pre-install the hand controls on a Thrustmaster wheel rim and ship the assembled unit to you. We'll work with you to select the wheel rim and provide an estimate on additional shipping and handling costs.

Installation OverviewOne of our primary goals for all hand control for Thrustmaster products is to minimize modification to your Thrustmaster components. In fact, there is no modification whatsoever done to the T300/TX servo base for any of our products. The installation is always done on the removable Thrustmaster wheel.

The below illustration demonstrates the basic concept of how the SimAbility GT Ring hand controls are installed between the stock Thrustmaster steering wheel and its threaded disconnect. Once installed, an external cable connects the hand controls to the pedal input on the back of the Thrustmaster base. All of the standard buttons and functions on the Thrustmaster wheel and base continue to work. And best of all, the Thrustmaster base sees the SimAbility hand controls just as if they were Thrustmaster pedals. This means you will retain compatibility across all platforms (PC and Console) that the base originally supported.

Throttle and Brake OperationThere are two configurations to choose from as shown below. Not sure which is best for you? No problem. It’s relatively easy to switch between the two modes. Typically 30 to 45 minutes to complete the change.

1) Pull Throttle (AKA Sim Racing Mode). This is the configuration preferred by nearly all customers. Here you operate the throttle by pulling the ring with one or more fingers. The brake is operated by pushing with your thumb, or even the palm of your hand.

2) Pull Brake (AKA Hardcore or Real Mode). This configuration emulates most real-world ring hand control systems such as Guidosimplex. In those systems, the pull ring is connected to the car’s brake pedal allowing the driver to utilize the grip of both hands to operate the brake. The throttle requires less force making it a good fit for the push ring.

Compatibility- Our hand controls are designed to emulate the stock Thrustmaster two-pedal unit. Meaning your Thrustmaster base will retain compatibility with the PC and Console games it was designed to support. - T300 Base: PC / PS3 / PS4 - TX Base: PC / Xbox One- Our hand controls can also be connected to most aftermarket controllers such as Derek Speare Designs, Leo Bodnar, and SIM Display. Anything that supports the Allegro A1302 Hall Effect sensors should work. At this time we have only tested and confirmed on the DSD 12-bit controller.- The GT Ring system can be installed on the below Thrustmaster Servo Bases. They should work on the T500 if the static paddles can be removed, and they should work on the new TS-PC Racer base but neither of these have been tested or verified. - Thrustmaster T300 (verified) - Thrustmaster TX (verified)- The GT Ring system can be installed on all Thrustmaster wheel rims where the threaded adapter can be removed. This excludes the stock TX (plastic) wheel and the F1 wheel. All other wheel rims will work.

GT Rings vs. Paddles

Is the SimAbility GT Ring system right for you? Your two basic options are paddles or rings. To help you decide, we’ve summarized the key advantages and disadvantages of the GT Ring system for most drivers.

Advantages of the GT Ring System

- Great feel and control of the push/pull rings.- Both rings can easily be operated throughout the full rotation of the wheel. This is beneficial for all games, but especially good for rally, dirt, and truck driving games that require a lot of steering input.- Easy to use an external shifter (H-pattern or sequential) because you can take one hand off the wheel and still have control of the gas and brake with the other hand!

Disadvantages of the GT Ring System

- More expensive than paddles.- Installation is generally more involved, although a pre installation option is available by request. The pre installation does incur additional shipping and handling costs.

Features

Progressive Brake Adjuster

Pictured here, the progressive brake adjuster is installed on the push ring top swing assembly which is the default configuration. If you decide to use your pull ring for brake, then you can simply move the aluminum arm and adjuster assembly to the bottom swing assembly so you’ll have the progressive brake adjuster on the pull ring.

Applying the precise amount of brake pressure is critical in real racing as well as sim racing. Although cost and space prevent us from utilizing hydraulic or load cell braking, we do our best to emulate those systems. In fact, this is another area where our hand controls exceed the quality of standard sim racing pedal sets.

We use a simple adjustable conical rubber to allow you to dial in that sweet spot. The adjuster simply moves the conical rubber up or down changing the point in which the aluminum arm contacts the rubber.

High Quality Hall Effect Sensors

We use Allegro A1302 5V Hall effect sensor along with a high quality Neodymium magnets on the throttle and brake sensors.

These sensors help us emulate the stock Thrustmaster potentiometers allowing your wheel to will retain compatibility with the PC and Consoles it was designed to support. They are also compatible with most aftermarket controllers for those hardcore PC gamers.

And of course, Hall sensors are far superior to the stock potentiometers because they will never wear out or get dirty. Your hand controls will always operate smoothly!

Adjustable Ring Positions

The Pull Ring placement has a wide range of adjustability. Each side of the ring mount has a machined slider for fine tuning along with three different holes for coarse tuning.

The Push Ring can also be adjusted inwards or outward, as well as slightly upward or downward.

The push ring is simply attached with two screws and can be replaced with a paddle or other plate design. It’s really open to DIY customization projects.

The static placement of the rings is highly adjustable. This primary applies to the larger pull ring allowing you to keep the pull ring in a comfortable location based on your grip.

Adjustable Ring Travel

The distance of travel for the pull ring and push rings are controlled independently by changing the “Travel Stop Blocks”. These blocks are made from High Density Polyethylene (HDPE) which means they are solid enough to provide a solid non-mushy stop, but soft enough to eliminate annoying clanking sounds when hitting the full on and full off stops.

Each wheel is supplied with a set of 35mm (1.38”), 30mm (1.18”), and 25mm (0.98”) travel stop blocks. (Smaller blocks are available by request). The measurements refer to the approximate distance each ring moves. The total travel will vary slightly due to other adjustments.

Carbon Fiber Shift Paddles

We provide carbon fiber shift paddles and mounts. This is actually a requirement because the bottoms of the stock paddles interfere with the hand controls. These custom replacement paddles are designed to improve the accessibility, functionality, and overall feel of the shift paddles. And of course the carbon fiber feels and looks great!

The shifter mounts are also designed with the DIY user in mind. The shift paddle height can be changed by replacing the standoffs. Also, an entirely different paddle could be fabricated and attached with two screws.

Changeable Springs

The compression springs can be independently changed for each ring. The available spring rates range from 1.4 lbs per inch to 4.1 lbs per inch.

The unit ships with a couple of extra springs and additional rates are available upon request. But because they are standard Losi RC car springs it’s probably easier to buy them locally, or on the Internet. Below are the Losi Part # and possible rates.
